The RS4 has been around since 1999. The new one presents the fourth generation. Delightful to compare it with the first one. What have nearly two decades of high-end A4 technology achieved?

One has landed after interim variations as a sedan and even convertible again at the Avant, and only at the Avant. The V8-top technology in the naturally aspirated engine with maximum speeds in excess of 8500/min, one has left. So there is the RS4 again with V6 Biturbo.

There are just over 200 cm³ more displacement, but the turbo technology, which has meanwhile been further developed, now makes 600 instead of 440 Nm possible, in addition starting 600/min earlier. In contrast, take 51 kW (70 hp) plus are more modest. The top speed could not be increased anyway, but is now optionally offered higher.

The empty weight has grown by almost 100 kg, but had to be compared with today because it was without driver. However, the car has also become about 25 cm longer, which has increased its luggage space by 30 at minimum and 20 percent at full load.

No, the air resistance has not been improved significantly, especially since the slightly larger cross section. And yet it has been possible to reduce the CO₂-value by a third, despite the increased performance. However, how the 127,000 DM are to be valued today compared to 80,000 euros, you have to judge for yourself. 02/18
